## What is FCC GROL & GMDSS Prep?

Study for five FCC commercial radio operator licences in one app: the General Radiotelephone Operator License (GROL), the GMDSS Radio Operator's and Restricted GMDSS licences, the Ship Radar Endorsement and the GMDSS Radio Maintainer's License. Pick your licence and the app draws the right exam elements.

Every question is the real, word for word FCC pool question with the official answer, plus a plain-English explanation written by us, so what you study is exactly what the exam tests.

WHAT YOU GET
- 2,224 real FCC pool questions from Elements 1, 3, 7, 7R, 8 and 9, each one explained
- 2,224 flashcards for the rules, formulas and GMDSS procedures you need cold
- A licence picker: choose GROL, GMDSS Operator, Restricted GMDSS, Ship Radar or GMDSS Maintainer
- Timed mock exams that gate each element at its official pass mark
- Weak-area review that resurfaces what you get wrong
- A readiness score for every exam topic

## Version history (last 4 releases)

### 1.3 — 2026-08-23

Element 8 is now complete.

The 20 Ship Radar Endorsement questions that depend on a diagram now ship with
their radar figures, taken from the official FCC pool document. Element 8 goes
from 280 to the full 300 questions, and the app now carries all 2,244 questions
and 2,244 flashcards across Elements 1, 3, 7, 7R, 8 and 9.

Every element now matches the official FCC pool exactly. A pool-completeness
check runs on every build to keep it that way.

Also in this update:
- Mock exams draw from the new questions automatically, including the figure
  questions, so a Ship Radar mock is now a full-pool draw.
- Corrected the question and flashcard counts shown in the store listing, which
  still quoted the pre-update figure.

### 1.2 — 2026-07-31

New in 1.2:
• New app icon and refreshed screenshots
• Redesigned home screen with revision reminders and a countdown to test day
• Question pool re-verified for the 2026 exam

- New licence picker: choose your licence and the mock draws the right elements, each gated at its official pass mark
